CNMG120412 QK3105 standard carbide (with coating) turning inserts with four cutting edges

C - quadrilateral shape of turnining insert - rhombic (80°)

N - Insert without clearance under main cutting edge (0°)

M - Tolerances and dimensions of carbide turning insert

G - Hole through insert and double sided chipbreaker

12 - Length of cutting edge 12,9mm

04 - Height (thickness) of insert 4.76mm (from bottom of the insert to the top of the cutting edge)

12 - Nose radius R1.2

QK3105 - ISO Grade K01-K10, P01-P10 - The type of carbide grade and the coating on inserts is originally intended for turning cast iron, but it also performs when turning other alloys.

• Material: ISO grade carbide (tungsten):
  • For steel P01-10 (best against wear resistance) (See ISO grade tables.)
    
  • For cast iron K01-10 (best against wear resistance) (See ISO grade tables.)
    
  • CVD coating - thicker less precise layer coating
• Feed speed mm/rev - 0.2-0.5
• Cut depth - 0.7mm - 5.0mm
• Cuting speed - 230 - 480m/min
• Turning insert feature:
  • Strong cutting edges best reliability in hard cuting conditions and long endurance.
  • Geometry of CNMG turning insert is shaped for strong turning.
    
  • Four cutting edges (when used properly, you can use it four times)
  • Inserts have secured and strongly supported cutting edge.
  • Recommended for different purposes and applications.

Tips and Tricks:

• For rough turning it is recommended  to use inserts with bigger nose radius (like R0.8 - R1.2), so wear, force and heat is distributed over larger surface - which makes inserts more durable.
  
• For finishing it is recommended to use inserts with smaller nose radius (like R0.8 - R0.4), with that we reduce preasure on insert, increase cutting abilities, reduce vibration and we make better finishing surfaces.
